To all whom zt/may concern.: f

Be it known that I, `ARTHUR MERRIGK BLAMPHIN, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Im rovements in Soil Boring and Sampling pparatus; and I do lhereby. declare the following to be a full, clear, and exact kdescription `of Ythe invention,-such as will enable yothers skilled inthe art -to which it appertains tomake and use the same. Y n This invention relatesto a soil boring and sampling apparatus, and has for its object to provide a means of thischaracter which will be simple in construction, comparatively inexpensive to manufacture, and more eiicient in use than those which have been heretofore proposed. Y

With these and other objects in view, the invention consists in the novel details ofconstruction and combinations of parts more fully hereinafter disclosed and particularlyv pointed out in the claims.

Referring tothe accompanying drawings forming a part of this specification', in which like numerals designate like parts in all the views: Figure 1 is a planview 'partially broken faway ofl an apparatus made in'accordance with this invention; Y

- Figure 2 is a ksectional view of the parts shown inFigure 1, withthe sampling tube removedfrom the boring head.;

Figure 3 is an enlarged sectional view of a portion of the parts shown in' Figure 1 with the sampling tube in its closed position on the Y boring head;

Figure 4 is a plan view of a rod and piston which' is used for' cleaning out th'e mud'or" other material fromthe sampling tube after it has been used; 4and Y Figure 5 is a sectional view taken'on the line 5-5 of Figure 3, looking in the direction of the arrows. ,Y

1 indicates any suitable'boring head, preferably of the cone shaped plug form illustrated and provided with the rather sharp point 2 and the shoulder 3 against which fits the lower end of the outer sleeve 4, preferably made of brass or other metal. To the boring head 1 is screw threaded as at 5 the rod 6 which extends upwardly a considerable distance above the tube 4 as shown in Figure 2, where it is joined to the chain 7 which extends up beyond the upper portion of the apparatus proper, as illustrated. The upper end -of the tube 4 is screw threaded as aty 8, and into said end'is fitted the plug ymember 9 provided with a screw threaded neck 10 to Whichis tted the lower end 11 of the tubular member 12 which is made -in sections 13 as shown in Figure l and each section isy provided with 'a coupling member-14 by which other sections 'may 'be screwed thereto. In this manner is the-tubular'portion 12 of the apparatus'made as long'as is convenient ory as is necessary to get a sample of the earth or soil being investigated. At the extreme upper portion of the apparatus'is a coupling such as 14 and the tube'4being closedy upon the'plug member l as indicated in Figure 1,l

the chain17 is drawntaut Vand-a'fplug such as 17-1s thrust through the chain to hold the parts :tightly together. That is'to say, it 'is necessary for the'joint 185Figure 3 to be held quite tight when the apparatus is sunk'into the soil in order to prevent water'and other material `from entering the chamber 19 and thus getting a false sample.y After the parts are thus secured firmly together as indicated in,l Figure 1, the whole apparatus is inserted into the ground either byyhan'd or' other pres-` sure, or fitm'ay'be driven into the ground in a mannerl similar to that employed in driving wells, etc. by meansnot attached to the instrument. Y I' f i After the apparatus has thus vbeen sunk below thek surface'Y of the'earth or soil being investigatedto the desired depth, the wedge is withdrawn `and a pull is exerted on ther outer casing 12 or 13 by any suitable means. Ifthe apparatus'isonly sunk to a relatively small distance in the ground this pull maybe exerted by hand, whiley if'it is sunk to a deeper distance, the pull may be exerted by Y a suitable power means.' TheV purpose of the pull is to separate the 'tube 4f'from the plug member l as indicated in Figure 2,`where upon the soil will naturally work' its way in of itself toward the rod Gand thus get in the out as is illustrated in Figure 2.

In orderto facilitate the extraction of the soil sample I prefer to place-inside the tube 4 a paraffined paper tube 25o-r otherv tube thatl Will bek impervious to Water and moisi ture, and to have this tube 25 of ksuchga size and dimensions as to enable the operator to. readilykremove the same from the tube 4- leaving. the soil in said tube 25. In fact, AI prefer to employ atube '25 .which will be suitable for mailing, so that I lmay, merely extract said tube 25 from the tube 4, and, fit suitablev closures to each end of said tube 25, label the same, place it in thel mails,and send it to` any v desired laboratory yfor an analysis or examination of the soil sample.

Bythis means,vI am enabled, `when'at outof-the-.Way places-that are inaccessibleto laboratories to obtain a sample in ay relatively verylshort time indeed, to" mail-the samev toa laboratory, and have :a report back at the Aplace of operation in a period of time which is only av fraction of that required to get the same results by other Well known means which were in use prior to..

this invention. Instead .of separating the parts as illustratedin Vligure 2 for the removal of the sample, and tube 25, of course the plug or head 1 may be readily unscrewed from the rod 6 and the tube. 25-extracted by` any-suitable'means or the saidplug 1 may be unscrevved as just described, as VWellJ as theplug member 9, so that the tube 4 will be open at each end and thus Will enable me to forcibly push out the tube .25 should,itstick'within the tube 4. This -forcible' removalrof the tubev25 can be effected Vby means of the disk 30 attached `to the rod 31,v or by other means. Y.

Of course it is further desirable to keep `the tube 4 as clean as possible for the taking oi other samples and. for the reception of new tubes 25, and thereforeI find the disk 3() and rod 31 to be very convenient in cleantime.

Of course, it is obvious that I am not to be confined to any material Whatever in making ,this apparatus, and further, it is obvious that those skilled in the art'may vary the details of construction as Well as the arrangement of parts Without departing from the spirit of the invention, and therefore I do not Wish to be limited to the above disclosure except as may be .required bythe claims.

What is claimed is:

1. In a soil sampling'apparatus'the combination of a cone shaped pointed head provided with a. shoulder; a rod secured to said. head;,an outer open ended tube, one endof which fit-s said shoulder; means to close the other end of said tube through rwhich said rod passes; a. tubular member secured to said means into which said rod passes; a chain attached to the end of said rod; and means to lock said chain to one of said sections'to hold said first named tube in con tact with said shoulder.

2.v In a soil sampling apparatus the combination of a cone shaped pointedfhead providedxwitha shoulder a rod secured to said head g an outer open ended tube, one end of which fits said shoulder; meansto close the` other endy of said tube ,through which said rod passes; a sample receiving tube disposed inside said first named tube; a tubular member secured to said means int-o which said rod passes; a chain attached ,to` the end of said rod; and means to lock said chain to one of said sections to hold said lirst-named tube-in cont-act with said shoulder.

3. In a soil sampling apparatus the combination of a cone shaped pointed head` provided vvith a shoulder;V a rod detachably` se-` cured to said head; an outer openl ended tube, one end of which ts said shoulder; detachable means to close .the otherend of said tube through Which said rod passes; a tubular member section detachably secured to saidmeans yinto which said lrod passes; a chain attac-hed to the end fof said-rod; a. soil p sample receivingV tubular member detach-A l ably disposed inside said first namedtube; andmeans tolock said chain to one ofl said sections to holdy said first named tube in contact With said shoulder.

In testimony whereof I aii-X my signature.

ARTHUR yMERRICK BLAMPHIN.
